To aZZ whom, it rita?! cm1/ecrit.-

Be it known that I, JOHN ALBERT MARCE- RON, a citizen of the United States, residing at Vashingtou, in the District of Columbia, have invented certain new and useful I1n provenients in IWindow -Screensg and I do hereby declare the lfollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements on window -screens and attachments therefor whereby they are lit-ted or secured to a window-opening which comprise a frame piovided with tongues and grooves at its ends, moldings or guide-strips having grooves and tongues and adapted to be fastened to opposite sides of a window-opening and with which the respective tongues and grooves on the ends of the frame are adapted to engage, and a springlocated between one end of the frame and the adjacent molding or guide-strip for pressing the other end of the frame into its seat in the other molding or guide-strip.

My object is to simplify the construction of such window-screens and attachments; and the invention consists in certain novel features of construction, hereinafter described, which enhance the value of such article by the readiness with which such windowscreen may be inserted and removed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure lis a front view of a part of a window-frame, showing my improved windowscreen and attachment-s in position, a part of the window-fram e, windowscreen,and attachment at the left-hand side being broken away to exhibit the seating-spring. Fig. 2is a hori- Zontal section, on an enlarged scale and looking downward, taken on the line m Qc, Fig. l. Fig. 3 is a similarsection showing the windowscreen as it appears when partly inserted or partly removed. Fig. et is a similar section showing the same as it appears when the spring end is partly inserted or is being entirely removed.

represents the jambs of a window-frame,

into the opening of which my attachments are securely fastened and my window-frame is removably secured.

c is a molding or guide-striplocated at one side ofthe winiilow-opening. This molding or guide-strip c is formed with a groove e and with two retaining-walls e' e ot equal width and equal depth.

CZ is a molding or guide-strip located at the other side of the window opening. This molding or guide-strip (Z is formed with a deep broad groove (Z, with a shallow rabbet CZ of less depth than the broad groove d', with a retaining-wall Zt', and with a narrow tongue g ot less `depth than the retainingwall Zt',

a is the frame of the window-screen, having end strips fr'. One end stripf is formed with a tongue j" and with a rabbet f". The other end strip/i is formed with a deep groove Zi., a broad tongue 7i", and with a narrow tongue 7i.

Z is a leaf or bow seating-spring secured to the face of the broad tongue 71. of the end strip t'. The tongue f on the end strip is fitted into the groove e in the molding or guidestrip c, whereby the frame is held at one end by the retaining-walls c e, the retainingwall c fitting into the rabbet f". The deep groove ZL on the other end strip t' is of greater width and depth than the narrow tongue g of the molding or guide-strip CZ, so as to leave suflicient room or play around the narrow tongue g between the broad tongue hl and narrow tongue h" of the end strip il to permit the window-screen a to be inserted when partly turned from the plane of the windowfraine into the opening between the moldings or guide-strips, the opening being of less breadth than the breadth of the windowscreen. The broad tongue 7L' is also of less width than the broad groove CZ for the saine purposeJ the leat' or bow spring' Z being compressed or spread within the broad groove CZ as the broad tongue ZL enters the broad groove (Z', and when the window-screen is partly turned on its spring end and arranged in the plane of the window-opening with all the tongues in line with their grooves and then released the spring will act and force the win- IOO dow-screen endwise and seat the tongue f at one end into its groove e in the molding or guide-strip c, while the broad tongue h at the other end of the window-screen is still lapped by the wall 7c of the other molding or guidestrip d and kept in place by the engagement of the spring Z with the narrow tongue g. The frictional contact ofthe springl with the molding or guide-strip d will hold the windowscreen at the desired height between the moldings or guide-strips on which the windowscreen is adapted to slide. The sprin g, being located within the broad groove d,is protected from the weather. If it is desired toinsert the window-screen at the other side of the windowframe to that shown in the drawings, the rabbet f will permit that corner ot' the windowscreen to pass the wall e of the adjacent molding or guide-strip c. To remove the windowscreen a, it is pushed toward the spring end to release the tongue f from the groove e at the other end and partly turned on the spring end and then withdrawn end wise from the molding or guide-strip d.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination ot' a molding adapted to be located at one side of a window-opening, a molding having a deep, broad groove,

a wall and a tongue of less depth than the wall, and adapted to be located at the other side of the window-opening, and a windowscreen comprising a frame adapted at one end to engage one of the molding-strips, and at the other end having a broad tongue of less width than the deep broad groove, a groove of greater width than the narrow tongue of the adjacent molding, and a seating-spring; substantially as described.

2. The combination of a molding having a groove and walls and adapted to be' located at one side of a window-opening, a molding having a deep, broad groove, a wall and a tongue of less depth than the wall,and adapted to be located at the other side of the windowopening, and a window-screen comprising a :frame having at one end a tongue, and, at the other end a broad tongue of less Width than the deep broad groove, a groove of greater width than the narrow tongue of the adjacent molding, and a seating-spring; substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
